Re: vro has to go

Peter.... Rather than buy another fuel pump, boaters who want to do away with the automatic oiling setup usually go the following route.<br /><br />(VRO Pump Conversion To Straight Fuel Pump)<br /><br />You can convert the VRO pump into a straight fuel pump, eliminating the oil tank and VRO pump warning system, but retain the overheat warning setup by doing the following:<br /><br />1 - Cut and plug the oil line at the engine so that the oil side of the VRO pump will not draw air into its system. Trace the wires from the back of the VRO to its rubber plug (electrical plug) and disconnect it.<br /><br />2 - Trace the two wires from the oil tank to the engine, disconnect those two wires, then remove them and the oil tank.<br /><br />3 - Mix the 50/1 oil in the proper amount with whatever quanity fuel you have. Disconnect the fuel line at the engine. Pump the fuel primer bulb until fuel exits that hose with the tint of whatever oil you used. Reconnect the fuel hose.<br /><br />That's it. If you want to test the heat warning system to ease your mind, have the key in the on position, then ground out the tan heat sensor wire that you'll find protruding from the cylinder head. The warning horn should sound off.

Re: vro has to go

That will be a faulty fuel pump. A small hole in the diapharm. Get a fuel pump kit. That will do it.

Re: vro has to go

Check the pulse line to the fuel pump for a restriction or leak first. Otherwise a new pump might do the same thing.
